如果您可以编译较少的文件,那么您可以使用这个按钮 mixin(来自mixins.less):
// Button variants
// -------------------------
// Easily pump out default styles, as well as :hover, :focus, :active,
// and disabled options for all buttons
.button-variant(@color; @background; @border) {
color: @color;
background-color: @background;
border-color: @border;
...
如果您查看buttons.less,您可以看到他们是如何使用它的:
.btn-default {
.button-variant(@btn-default-color; @btn-default-bg; @btn-default-border);
}
.btn-primary {
.button-variant(@btn-primary-color; @btn-primary-bg; @btn-primary-border);
}
// Warning appears as orange
.btn-warning {
.button-variant(@btn-warning-color; @btn-warning-bg; @btn-warning-border);
}
// Danger and error appear as red
.btn-danger {
.button-variant(@btn-danger-color; @btn-danger-bg; @btn-danger-border);
}
// Success appears as green
.btn-success {
.button-variant(@btn-success-color; @btn-success-bg; @btn-success-border);
}
// Info appears as blue-green
.btn-info {
.button-variant(@btn-info-color; @btn-info-bg; @btn-info-border);
}
